The thickness of each surface is preferably 0.05 mm to 10.00mm, more preferably 0.10 mm to 5.00 mm.

[Lid]

As shown in FIG. 1 and FIG. 2 , the lid 2 includes a lid main body 21and a small lid 22.

(Lid Main Body)

The lid main body 21 is formed of PE (polyethylene), PP (polypropylene),PET (polyethylene terephthalate), ABS resin or the like, for example.The lid main body 21 is formed as one by injection molding, two-colormolding, blow molding, or the like. The lid main body 21 is in acylindrical shape in which a lower surface is open. The lid main body 21includes a top surface 21 a, a lateral surface 21 b, a recessed portion21 c that is formed to be recessed downward on an inner circumferentialside in a plan view of the top surface 21 a, a hole portion 21 d, and amain body side wall 21 e that is provided to stand in a cylindricalshape so as to surround the hole portion 21 d inside the recessedportion 21 c.

The lid main body 21 is formed in a cylindrical shape that is a circlein a plan view with a diameter of preferably 60 mm to 200 mm, morepreferably 65 mm to 110 mm, and that is preferably 15 mm to 50 mm, morepreferably 33 mm to 45 mm in the Z-axis direction (height direction).The thickness of each surface is preferably 0.05 mm to 10.00 mm, morepreferably 0.10 mm to 5.00 mm.

(Top Surface)

As shown in FIG. 1 and FIG. 2 , the top surface 21 a is a portion on theouter circumference side other than the recessed portion 21 c on theupper surface of the lid main body 21 formed in a cylindrical shape.

(Lateral Surface)

As shown in FIG. 1 and FIG. 2 , the lateral surface 21 b is a portionthat forms a lateral surface of the lid main body 21 formed in acylindrical shape.

A female screw portion 211 in which the male screw 11 of the containerbody 1 screws is provided on the inner circumferential surface side ofthe lower end of the lateral surface 21 b. With this, as shown in FIG. 2, the container body 1 and the lid 2 have an attachable and detachableconnection structure via the male screw portion 11 and the female screwportion 211. Consequently, the lid 2 can be detached from the containerbody 1.

(Recessed Portion)

The recessed portion 21 c is formed to have substantially the same shapeas the small lid 22 in a plan view when the small lid 22 is closed, sothat the small lid 22 can be fitted to the recessed portion 21 c. Therecessed portion 21 is formed to have a front end larger than the frontend of the small lid 22 in a plan view so as to leave a slight gap evenin a state in which the small lid 22 is fitted to the recessed portion21 c. Thus, it is possible to hook a finger on the small lid 22 by usingthe gap.

(Hole Portion)

The hole portion 21 d is a hole formed in a circle in a plan view insubstantially the center in a plan view of the lid main body 21 andleading to the inside of the sanitary tissue paper storage container100. The hole portion 21 d is formed to be slightly smaller than theoutlet portion 3 in a plan view and the outlet portion 3 is fixed to thehole portion 21 d as described later.

(Main Body Side Wall)

The main body side wall 21 e is formed to protrude upward in acylindrical shape inside the recessed portion 21 c so as to surround thehole portion 21 d. The main body side wall 21 e is formed to have anouter diameter the same as or slightly smaller than an inner diameter ofthe small lid side wall 22 a formed in the small lid 22.

(Small Lid)

The small lid 22 is formed of PE (polyethylene), PP (polypropylene), PET(polyethylene terephthalate), ABS resin or the like, for example. Thesmall lid 22 is formed as one by injection molding, two color molding,blow molding, or the like. The small lid 22 includes a small lid sidewall 22 a protruding from the surface on the lower side when the lid isclosed. The small lid 22 is formed such that the shape in a plan viewwhen the small lid 22 is closed substantially matches with the recessedportion 21 c. With this, the small lid 22 can be fitted to the recessedportion 21 c when the small lid 22 is closed.

(Small Lid Side Wall)

The small lid side wall 22 a is formed in a cylindrical shape extendingdownward when the small lid 22 is closed. The small lid side wall 22 ais formed to have an inner diameter that is the same or slightly largerthan the outer diameter of the main body side wall 21 e. When the smalllid 22 is closed, the small lid side wall 22 a comes into contact withan upper surface of the recessed portion 21 c. With this, when the smalllid 22 is closed, the small lid side wall 22 a can fit to the main bodyside wall 21 e. Consequently, it is possible to maintain airtightness ofthe space surrounded by the small lid side wall 22 a and the main bodyside wall 21 e, and thus maintain airtightness inside the sanitarytissue paper storage container 100 connected to the above space via thehole portion 21 d.

According to the present embodiment, the airtightness inside thecontainer body 1 is maintained by fitting the main body side wall 21 ewith the small lid side wall 22 a. Alternatively, a configurationdifferent from the above can be employed as long as the airtightnessinside the container body 1 can be maintained.

If the stored sanitary tissue paper is not soaked in a chemical solutionor the like and there is no need to avoid drying, the configuration doesnot need to be provided with measures for airtightness.

(Outlet Portion)

As shown in FIG. 3 and FIG. 4 , the outlet portion 3 is an elasticallydeformable member (outlet member) that is formed in a substantial pillarshape which is a circle in a plan view. FIG. 4 is a bottom view of anoutlet portion 3 and shows a state viewing the outlet portion 3 shown inFIG. 3 from below.

Specifically, the outlet portion 3 includes a recessed portion 31 whichincludes an inner bottom surface 3 a formed in a center in a plan view,a narrow portion 32 formed on the lateral surface, an outlet 33 formedin a substantial center in a plan view of the recessed portion 31 (innerbottom surface 3 a), and a chamfered portion 34 formed by chamferingperipheral portions of the outlet 33 on a lower surface 3 b.

The outlet portion 3 is formed so that the thickness R1 of the outletportion 3 in the Z-axis direction below the narrow portion 32 (dimensionbetween the inner bottom surface 3 a and the lower surface 3 b) (seeFIG. 5 ) is 1.0 mm to 5.0 mm, preferably 1.5 mm to 3.0 mm.

(Recessed Portion)

The recessed portion 31 is formed on the upper surface of the outletportion 3. The recessed portion 31 is formed to be in a shape recesseddownward in a circle shape from a plan view, with the peripheral portionremaining. The recessed portion 31 is formed so that the inner bottomsurface 3 a is flat.

The recessed portion 31 is formed so that the inner bottom surface 3 ais flat.

(Narrow Portion)

The narrow portion 32 is formed in a groove shape recessed in a radialdirection to have a depth that is equal to or larger than one twentiethand equal to or smaller than one tenth of the diameter of the outletportion 3 in a plan view, surrounding the substantial center portion inthe up-down direction of the lateral surface of the outlet portion alongthe circumferential direction. Since the outlet portion 3 is formed tobe slightly larger than the hole portion 21 d in a plan view, by fittingthe edge of the hole portion 21 d into the narrow portion 32, it ispossible to fix the outlet portion 3 to the lid main body 21.

(Outlet)

The outlet 33 is a hole for taking out the sanitary tissue paper storedinside the container body 1.

The sanitary tissue paper is inserted through the outlet 33 from thelower surface 3 b side, and the outlet 33 holds the sanitary tissuepaper with its end protruding from the upper surface of the outletportion 3 (inner bottom surface 3 a of the recessed portion 31).

When the end of the sanitary tissue paper is in a state protruding fromthe upper surface of the outlet portion 3, the protruding amount is 5 mmto 39 mm, preferably, 13 mm to 20 mm. Since the protruding amount isequal to or more than 5 mm, the sanitary tissue paper can be easilypicked by fingers of an average user, and the sanitary tissue paper canbe taken out easily. Since the protruding amount is equal to or lessthan 39 mm, the end of the sanitary tissue paper does not pop out whenthe lid 2 is closed.

The outlet 33 is formed by a cut portion 330 in which two straight linesintersect in a cross shape at the substantial center of the outletportion 3 in a plan view.

For example, as shown in FIG. 4 , the cut portion 330 includes fourstraight line portions 331, a first circle portion 332 that is providedin a portion where one end of the straight line portion 331 intersects,and a second circle portion 333 that is provided in the other end of thestraight line portion 331 and that has a diameter smaller than the firstcircle portion 332.

An entire length of the cut portion 330 is formed to be 5 mm to 30 mm,preferably 10 mm to 15 mm. For example, the entire length is set to beabout 15 mm which is equal to or larger than the width of an indexfinger of a typical user. As described above, by forming the cut portion330 to be a cross-shaped cut, the sanitary tissue paper can be morereliably held by the cut portion 330.

The diameter of the first circle portion 332 is formed to be 2.5 mm to4.0 mm. By providing such first circle portion, the appearing portionheld by the outlet portion 3 after the sheet is taken out can be madelonger. By providing the second circle portion, the sheet can be takenout with less force.

FIG. 4 illustrates and describes an example in which the outlet 33 isformed in a cross shape. However, the shape of the outlet 33 is notlimited to the above, and any shape can be selected if the abovefunctions can be fulfilled. That is, a radial cut may be formed by threeor more cuts in a straight line. The outlet 33 can be formed by one cutin a straight line, or can be formed in a circular shape, an oval shapeor a substantial star shape.

(Chamfered Portion)

As shown in FIG. 4 and FIG. 5 , the chamfered portion 34 is a regionobtained by chamfering the corner formed by the lower surface 3 b of theoutlet portion 3 and a hole wall 33 a of the outlet 33.

Specifically, the chamfered portion 34 is a flat chamfered portionobtained by chamfering the edge of the hole wall 33 a of the outlet 33in the lower surface 3 b of the outlet portion 3 with an inclined flatface. Thus, the outlet 33 has a shape in which an opening area on thelower end side is larger than the opening area on the upper end side.

As shown in FIG. 6 , the size of the chamfered portion is preferably setsuch that a length L1 in a width direction (direction along an XY plane)of the outlet 33 from the hole wall 33 a of the outlet 33 is within arange of 0.5 mm to 1.0 mm, and a length L2 in a height direction(direction along the Z-axis direction) from the lower end of the outlet33 is within the range of 0.5 mm to 1.0 mm.

Here, an example of forming the chamfered portion by chamfering to be aflat face is described by illustration. Alternatively, as shown in FIG.7 , the chamfered portion 34 may be a curved chamfered portion obtainedby chamfering the corner which is formed by the lower surface 3 b of theoutlet portion 3 and the hole wall 33 a of the outlet 33 to be a convexcurved surface.

The outlet member used to form the above described outlet portion 3needs to be able to be inserted in the hole portion 21 d. The outletmember also needs to be not detached from the lid main body 21 when thesanitary tissue paper storage container 100 is used. Moreover, it isnecessary that the sanitary tissue paper can be pressed in the outlet 33with the finger. In view of the above, the outlet member needs to beformed using a material including a certain degree of elasticity.Specifically, preferably, the hardness is from 50 to 70. The hardness ismeasured by JIS K 6253 (type A durometer).

Specifically, for example, elastomers such as styrene-butadiene type,polyester type, polyethylene type, and urethane type can be used, andthe outlet member is formed by injection molding.

When color is added to the outlet portion 3, for example, a resin suchas PE (polyethylene) mixed with any pigment is mixed with the elastomer(pigment adding process). Here, by changing a ratio of mixing theelastomer and the PE which is resin, the performance of the outletportion 3 for taking out the sanitary tissue paper can be adjusted.

Here, the resin mixed with the elastomer should have a higher hardnessthan the elastomer.

When the force necessary to pull out the sanitary tissue paper from theoutlet portion 3 is measured five times using a digital force gauge(manufactured by IMADA, model DS2-200N) and the average value is definedas a resistance value, preferably, the value of the resistance value iswithin a range of 5 N to 12 N, more preferably from 6 N to 10 N.

When the sanitary tissue paper rolled in one roll (for example, 80sheets are connected with 79 perforations) is pulled out, the allowablerange of the number of times that the subsequent sanitary tissue paperis continuously pulled out without the perforation being cut (number oftimes of linking) is 10 times or less, preferably 7 times or less.

Though the embodiment according to the present invention has beendescribed in detail, the present invention is not limited to the aboveembodiment, and modifications can be made within the scope of thepresent invention.

For example, the sanitary tissue paper stored in the sanitary tissuepaper storage container 100 is not necessarily limited to a rolledsheet. So-called pop-up sheets in which sheets are alternately layeredon each other and which is formed so that the next sheet of sanitarytissue paper is pulled out to the outlet 33 when one sheet of sanitarytissue paper is taken out can be employed.

The shape of the sanitary tissue paper storage container 100 does nothave to be a cylindrical shape, and may be a prismatic shape that ispentagonal, hexagonal, etc. in plan view, for example.

EXAMPLE

Next, the following description describes the result of evaluating thechange of the performance of taking out the sanitary tissue paper due tothe change in the mixing ratio of the elastomer and the PE in the outletportion 3. Below, the present invention is specifically described by theexamples, but the present invention is not limited to these examples.

[Sample Preparation]

As the sanitary tissue paper storage container 100, a PE containershaped as shown in FIG. 1 and including a container body 1 and a lid 2that is detachably attached to the container body 1 is prepared.

The outlet portions 3 according to the following examples 1 to 5 areattached to the lid 2 of the sanitary tissue paper storage container100.

The outlet portion 3 is shaped as shown in FIG. 3 to FIG. 7 , and thethickness in the Z-axis direction is 3.0 mm with the exception of therecessed portion 31. The hardness of the outlet portion 3 based on themeasurement by the type A durometer in accordance with JIS K 6523 is58.3.

The outlet 33 is shaped in a cross-shape in a plan view as shown in FIG.4 , and the entire length of the outlet 33 is 29 mm viewed from above.

The lengths L1 and L2 of the chamfered portion 34 are set to beL1=L2=0.5 mm and L1=L2=1.0 mm in the Examples 1 and 2, respectively.

The other conditions are the same as in Example 1.

Example 4

The outlet portion 3 is made by mixing an elastomer with PE in a ratioof 100:7.5. The elastomer includes a styrene thermoplastic elastomermixed with an acrylic elastomer.

Here, the hardness of the outlet portion 3 based on the measurement bythe type A durometer in accordance with JIS K 6523 is 59.1.

The other conditions are the same as in Example 1.

Example 5

The outlet portion 3 is made by mixing an elastomer with PE in a ratioof 100:10. The elastomer includes a styrene thermoplastic elastomermixed with an acrylic elastomer.

Here, the hardness of the outlet portion 3 based on the measurement bythe type A durometer in accordance with JIS K 6523 is 60.5.

The other conditions are the same as in Example 1.

The following tests were performed using the sample including the outletportions 3 prepared as described in the above examples 1 to 5.

[Test 1. Change in Performance Due to Change in Hardness of OutletPortion]

The sanitary tissue paper which is a rolled wet sheet in which 80 sheetsare linked with 79 perforations provided at a predetermined interval inthe length direction is stored in the container body 1 of the sanitarytissue paper storage container 100 provided with the above samples.

Next, the lid 2 is attached so that the end of the sanitary tissue paperprotrudes from the outlet 33. The protruding end of the sanitary tissuepaper is pulled out upward and a test of taking out all 80 sheets of thesanitary tissue paper is performed 5 times for the outlet portions 3 ofeach example. The following items are measured (1) number of times offalling, (2) number of times of linking, (3) average length of appearing(4) standard deviation (5) suitable appearing percentage, and (6) crossportion resistance.

(1) Number of Times of Falling

After the sheets are pulled using each sample, the average value of thenumber of times that the outlet portion 3 could not fully hold the endof the sanitary tissue paper and the sanitary tissue paper fell in thecontainer body 1 is calculated as the number of times of falling.

(2) Number of Times of Linking

When the sheets are pulled out using each sample, the average value ofthe number of times that the subsequent sheet came out without being cutat the perforations is calculated as the number of times of linking.

(3) Average Length of Appearing

After the sheets are pulled out using the samples, the average value ofthe length of the end of the sanitary tissue paper held by the outletportion 3 is calculated as the appearing average length.

(4) Standard Deviation

The standard deviation of the average length of appearing as describedin (3) is calculated.

(5) Suitable Appearing Percentage

After the sheet is pulled out using each sample, the percentage that thelength of the end of the sanitary tissue paper held by the outletportion 3 is within the range of 5 mm to 39 mm which is the suitableprotruding amount is calculated as the suitable appearing percentage.When the length is equal to or less than 4 mm, it is difficult for theuser to pick, and if the length is equal to or more than 40 mm, thesheet may stick out when the small lid 22 is closed.

(6) Cross Portion Resistance

When the sheets are pulled out using each sample, the average value ofthe power necessary to pull out the sheet measured using the digitalforce gauge (manufactured by IMADA, model DS2-200N) is calculated as thecross portion resistance.

The results of the tests are shown in Table I.

TABLE I EXAM- EXAM- EXAM- PLE 1 PLE 2 PLE 3 ELASTOMER:PE 100:5 100:5100:5 HARDNESS 58.3 70 80 NUMBER OF TIMES OF 1.8 2.8 3.0 FALLING (TIMES)NUMBER OF TIMES OF 5.8 0.5 0.0 LINKING (TIMES) AVERAGE LENGTH OF 21.016.9 17.0 APPEARING (mm) STANDARD DEVIATION 20.5 11.0 10.4 SUITABLEAPPEARING 81.2 85.5 88.2 PERCENTAGE (%) CROSS PORTION 6.7 8.8 13.8RESISTANCE (N)

[Evaluation]

By comparing the examples 1 to 3 shown in Table I, it is possible tounderstand that the performance to take out the sanitary tissue paper bythe outlet portion 3 greatly changes when the hardness is changed.Specifically, as the hardness is increased, the number of times oflinking and the suitable appearing percentage are improved, and thevariation in the length of appearing becomes small. However, the numberof times of falling worsens and the cross portion resistance valueincreases.

This is presumably because due to the hardness increasing, and theresistance on the sheets becomes too large.

[Test 2. Change in Performance Due to Change in Mixing Ratio ofElastomer and PE in Outlet Portion]

Next, the results of the tests performed for the samples correspondingto the examples 4 and 5 similar to the tests 1 are shown in Table II.

TABLE II EXAM- EXAM- EXAM- PLE 1 PLE 4 PLE 5 ELASTOMER:PE 100:5 100:7.5100:10 HARDNESS 58.3 59.1 60.5 NUMBER OF TIMES OF 1.8 1.8 0.8 FALLING(TIMES) NUMBER OF TIMES OF 5.8 1.8 2.8 LINKING (TIMES) AVERAGE LENGTH OF21.0 22.8 22.6 APPEARING (mm) STANDARD DEVIATION 20.5 17.5 18.5 SUITABLEAPPEARING 81.2 83.2 76.5 PERCENTAGE (%) CROSS PORTION 6.7 7.0 7.1RESISTANCE (N)

[Evaluation]

Comparing the examples 1 and 4 in table II, by increasing the percentageof PE included in the outlet portion 3, it is possible to understandthat the number of times of linking is improved with the resistancevalue in the cross portion hardly changing.

This is presumably because the sheet is easily cut by increasing theresistance provided on the sheet.

Comparing the example 1 with the examples 4 and 5, it is possible tounderstand that the number of times of falling is improved with thepercentage of PE included in the outlet portion 3 increasing.

This is presumably because the sheet is easily cut by increasing theresistance provided on the sheet.

[Effects of Embodiments]

According to the sanitary tissue paper storage container 100 of thepresent embodiment, the outlet portion 3 is provided by mixing theelastomer with the PE. By changing the mixing ratio of the abovecomponents, the hardness of the outlet portion 3 can be finely adjusted,and the performance to take out the sanitary tissue paper can beadjusted.

Normally, when the elastomers are colored, a mixture in which pigmentsare mixed in the PE is mixed in the elastomer. Therefore, theperformance to take out the sanitary tissue paper by the outlet portion3 can be easily adjusted by only changing the mixing ratio withoutconsuming excessive time or cost such as adding processes or changingmaterial.

Specifically, by changing the mixing ratio of the elastomer and the PEfrom 100:5 to a range from 100:7.5 to 100:10, the falling of the sheetbecomes more difficult and the linking of the sheets becomes moredifficult meaning the above are improved.

By changing the type of elastomer used as the material, different fromchanging the hardness of the outlet portion 3, even if the perforationsof the sanitary tissue paper are adjusted so as to be easily cut, thechange in the resistance value of the outlet 33 (corresponding to crossportion in the embodiment) can be suppressed, and the ease of pullingout the sanitary tissue paper from the sanitary tissue paper storagecontainer 100 can be maintained substantially the same.
